Looking for location of electric fuel shutoff on 60 series with manual injectors. Any thoughts?
60 series with "manual" injectors? You have something confused here. The 60 series engines had electronic injectors that were on or off to control fuel flow.Looking for location of electric fuel shutoff on 60 series with manual injectors. Any thoughts?
Also check the 2 fuses that feed the ECM, some are in the battery box, some are elsewhere depending on the truck manufacturer.If a 60 series won't start, first place to look is at all the grounds. Batteries, frame, engine, all of them. Of course, this is after you make sure there is fuel in the tank, lol.
Actually series 60 injectors are mechanical unit injectors electronic controlled .60 series with "manual" injectors? You have something confused here. The 60 series engines had electronic injectors that were on or off to control fuel flow.
The older 2 stroke Detroits and the 8.2L engines had mechanical governors and fuel racks that controlled the injectors, some of those had electric solenoids to let the engine run or shutdown.
The restrictor fitting doesn't have a check valve in it but if the motor had one it would be screwed on the fitting or on the other end of the fuel return line.Yes 92.. its on the back of the head.. looks like a regular old brass outlet fitting.. but has a check valve in it..

the later 71 and 92 motors used a electronic fuel control on a mechanical unit injector ,no rack or governor but both use a camshaft and rocker to manually inject fuel.

Good to hear you found it. I spent Monday chasing an overheat shutdown on one. Showed a high coolant temp code, turned out to be a shorted wire on the OIL temp sensor. Apparently oil and Coolant high temp are the same thing to this engine.ECM lost power, broken wire inside harness. Thanks for thoughts
